The hydrogen added on the end of the formula is an indication that NAD has been reduced. As you read in the textb0ook section on oxidative phosphorylation, a series of redox reactions oxidize NADH back to NAD. All redox reactions are paired oxidation and reduction reactions, so what was reduced? Ultimately O2 is reduced to H2O (note the addition of hydrogen due to reduction). Oxygen is said to be the final electron acceptor, as no further redox reactions take place. In lab we will again look at differences among bacteria in their metabolism as a way to distinguish different species. First we will look at anaerobic respiration. When oxygen levels are low, some microbe can use a different compound than oxygen as their final electron acceptor. Sulfate SO,, carbonate CO3²", and nitrate NO; are all common alternatives, rich in oxygen, which can accept those electrons.…arrow_forward
